The tyres are the most used and most underestimated parts of a vehicle. Tyres are very important as the narrow tyre surfaces are the only contact between the vehicle and the road.
The service life of tyres is dependent on tyre pressure, driving style handling and fitting.
The tyres and wheel rims are an essential part of the vehicle's design. The tyres and rims approved by Volkswagen are specially matched to the characteristics of the vehicle and make a major contribution to good road holding and safe handling.
Avoiding damage to the tyres
Tyres with directional tread pattern
Tyres with directional tread pattern have been developed to roll in one direction only. An arrow on the tyre sidewall indicates the direction of rotation on tyres with directional tread вЂ‰ . The direction of rotation must be adhered to. This is the only guarantee for optimum grip and helps to avoid aquaplaning, excessive noise and wear.
If, however, the tyre is fitted in the opposite direction to the tread pattern, you must take more care when driving as the tyre is now no longer being used according to its designation. This is particularly important on wet roads. The tyres must be replaced as quickly as possible or be fitted with the tread in the correct direction.
Rotating wheels front to rear (does not apply to the CrossTouran)
A regular rotation of the wheels as shown in the illustration вЂ‰ is recommended to ensure a uniform level of wear for the tyres. All the tyres will then last for about the same time.
Volkswagen recommends having the wheels changed by a qualified workshop.
Rotating wheels front to rear (CrossTouran only)
The tyres and wheels fitted are of different sizes at the front and rear. Tyres and wheels on the front axle must never be exchanged for wheels and tyres from the rear axle (and vice versa).
Volkswagen recommends having the wheels changed round by a qualified workshop вЂ‰.
Tyres which are older than 6 years
Tyres age through physical and chemical processes which can impair their function. Tyres which are stored unused for an extended period will harden and become brittle more quickly than tyres which are in constant use.
Volkswagen recommends replacing tyres which are older than six years with new tyres. This also applies for tyres, including the spare wheel, which appear to still be in good condition and whose tread depth has not yet reached the minimum value stipulated by legislation вЂ‰.
The age of a tyre can be determined by the manufacture date, which is a component of the tyre identification number (TIN) вЂ‰ .
Mark tyres before you remove them to indicate the direction of rotation. This ensures you will be able to mount them correctly when you replace them (left, right, front, rear). When removed, the wheels or tyres should be stored in a cool, dry and preferably dark place. Do not store tyres mounted on the rim vertically.
Any tyres without wheels should be protected against dirt and stored standing on the tread.
WARNINGChanging wheels and tyres incorrectly could reduce vehicle safety and cause accidents and severe injuries. It could also invalidate the vehicle's type approval.
WARNINGCorrosive liquids and other substances can cause visible and non-visible damage to the tyres, which could cause the tyre to burst.
WARNINGOld tyres вЂ“ even if they have not been used вЂ“ can suddenly lose pressure or burst, especially at high speed, and thus cause accidents and serious injuries.
Old tyres should be disposed of as required by legislation.
